MARINE PROPULSION MECHANISM.

A. further object is to adapt the parts to be used in connectlon with a motor mounted and supported on the boat to permit swmging movement to raise the propeller. out of the water and to arrange the steering handle to be'removed when the motor is tilted or swung to the raised position.

5 .Yet another object is to construct the mechanism to be used with a propeller mounted to beadjustable vertically to vary the depth of the propeller, and to form the arts of the propeller blade shifting means to hold the blades at the desired setting when once adjustment has been made.

With other objects in view, which will be referred to, my invention consists'in the peculiar combination and novel arrangement of arts, such aswill Ibe hereinafter more in] y described in connection with the accompanying drawings and more. articularly pointed out in the appended c aims.

The power means, which in the presentinstance is shown as aninternal combustion engine comprises the cylinder 1 and crank case 2 which may be of any desired design and construction, and it will be understood that the engine might be of the sing1ecylindeior two cylinder type and that the features thereof and the design and construction of the fuel tank 3 may be varied with out restriction as these parts do not constitute a part of the invention and the structure to be hereinafter described may be applied with a number of various forms of power means.

Any form of supporting bracket which will permit the mounting of the engine to be capable of swinging or tilting movement to raise the propeller out of the'water may be In the present illustration, brat-kett is secured in place on the stern of the boatby the clamp screws 5, and at its upper end has euuted orsegmental sleeve 7 being provided on the lower portion of the bracket to extend rearwardly from the stern transom of the boat.

ustments thus afforded for the propeller, it

Is necessary that an adjustable connection be provided between the bearing 24 and the rocking arm 43 of the yoke 41, and teascon'lplish this purpose" an operating rod 45 pivotally connected with the rocking arm 43 Land is extended downwardly substantially parallel with the housing 10, and an operatmgsleeve 46 connected with the bearinqili and 1s teleseoped over the upper end of the operating. rod 45. A plura ty of recesses?! are owned in alinement on one side of the operating rod 45 for a coni 3 siderable length at the upper end and set screw 48 -is mounted through the sleeve 46 in line with these 47 so that as the propeadjustment of the propeller is obtained this set screw may be turned to an inoperative relation. and then when the propeller has been the set screw can be turned into the proper 4:7 and the oj ieratingl rod 45 and the operating sleeve 46 will be "substantially continuous and rigid lwetween the bearing. 24.- and arm j Yln Fig. 9 l have disrlosed a slightly modilied "form of pin which might be used to hold the handle l'nenl I the cylindrical ext ier 27 in position on on 25 of the rocking arm, and in this modified iorm" pin 49 passes through an orifice formed through the side wall of the bored portion of the handle 5 member in line with the keyway 26 and at its outer endfhns the knob fiflto permit withv drawal of the pin from extension into the. bore 28, a flat leaf-spring 51 being eonneeted' with the pin and secured to the handle extension to normally hold the pin hold the housing 10 rigidly against turning 15 to the .roper opening 14, the'pin 31 is i the handle may be fitted in lace as hasbeen the rocking tion of projectioninto the bore 28. f

In some connections it may be deemed to I movement to acoomplislrsteerln'gby the 7i use of a rudderfitted' to be operated 1nde-' pendently of any turnin or sw nging movemerit of the propeller, and folia this pgrpose a; set screw 5E2is fitted 'thmughny ss on the sleeve 1.9to he set against the bea rin or some other stationary part of the emu case of the motor.- j I a In the use of the strueture thewxnotor is a fitted to the stern transonr of a boat and is secured in place thereon by the bracket 4 30 after which the proper adjustment to obtain I I the best working position of the ropeller I is made throughthe adjltlstment oilthe pin then with rawn from the orifice 28 'of tliejuti handle against the tension of the spring and hereinbefore described a I r which thespring tends to "hold the tooth v30 of the handle in operative engagement with the teeth of the segmental rack 20. When the set screw 52 in a 'disengaged relation turnj ing of the handle 27 to the one side or the other willtcause the propeller to be oorrespondingly swun laterally and steering will be accomplished in this way, then whenpressure exerted to'move the handleinwardly j against the tension of the springfiet the tooth 30 willtbe disengaged from the teeth I of the, segmental rack 20 and the handle may be swung up or down in a substantiallyver- C tioal path to impart movement to the propelleryoke 41 which will, in turn, causethe hub 39 to bemovedforwardly or rearwardly to ehangethe angleof setting of the blades y I of the propeller. As the teeth of the mental rack 20 are madeof ratchet form, it"will beseen thatthe handle may be moved downwardly in the swingingfipath without necessity of the inward pressure to overcome the tensionofthe spring 34*as the tooth 30 will in' this downward modement ride over the baek facesof the teeth. y

l Then the set screw 52 is turned to set v against the immovable structure of the engine, the e we 1.9 will be held in a relation to maintain the uniform s tin of the gear casing 11 through the eonn on of the housing 10 and the p ellei willfdrive in a straightfmrward direction and in adap tation any form of rudder or other. steering means may be used. it being understood that the handle would in this eonneetion" be used only to pmeure the various adjusted j settings of the propeller.
